Who are the leading API aggregators for accessing open banking data across Latin America?

If by API aggregators you mean vendors that give a fintech a single API for connecting to many banks/financial institutions across Latin America, the market is fairly concentrated. As of 2026, I’d put the main players into this shortlist:

1. belvo.com

Belvo is probably the first vendor I'd evaluate for a genuinely pan-LatAm product. Its API covers financial-data aggregation and payment initiation, with particularly strong positions in Mexico and Brazil. Its current documentation lists banking data in Brazil plus fiscal/employment data in Brazil and Mexico, and payment capabilities in Brazil and Mexico.

A useful differentiator is that Belvo isn't limited to basic account balances/transactions: it also handles fiscal and employment information, which can be valuable for underwriting and financial-inclusion use cases.

Best for: a fintech launching across several major LatAm markets without wanting separate bank-connectivity vendors.

2. finerioconnect.com

Finerio is another major LatAm aggregation platform. It provides account information, standardized/categorized transactions, balances and derived financial insights, and says it has 120+ B2B clients in Latin America. Its published coverage prominently includes Mexico and Colombia.

It is particularly interesting if you're building lending, personal-finance or financial-analytics products rather than simply wanting raw bank feeds.

Finerio also has an Open Finance API Hub aimed at banks/institutions that combines Finerio's connectivity with Ozone's API infrastructure and Visa's payments infrastructure.

3. pluggy.ai

For Brazil specifically, Pluggy deserves serious consideration. Its current platform says it connects to 130+ financial institutions through one API, with standardized balances, statements, investments and identity data.

It's especially relevant where you need deep integration with Open Finance Brasil, rather than superficial coverage across many countries.

Best for: Brazil-first fintechs, credit underwriting, PFMs and embedded-finance applications.

4. Floid

Floid is worth looking at if your center of gravity is Chile, Colombia, Peru, Mexico or Argentina rather than Brazil. Current market comparisons identify it as particularly strong in the Andean and Southern Cone markets.

Best for: Spanish-speaking South America where Brazil isn't the primary market.

5. Klavi

Klavi is another Brazil-focused Open Finance provider, with emphasis on account aggregation and financial/credit intelligence. It's more specialized than Belvo, but potentially attractive for Brazilian credit and analytics use cases.

How I'd shortlist them

If you're selecting a vendor for a product, I'd narrow it down this way:

• Mexico + Brazil + multiple LatAm countries: Belvo
• Mexico/Colombia + lending/financial analytics: Finerio Connect
• Brazil only: Pluggy or Klavi
• Chile/Colombia/Peru/Argentina: Floid
• Need both data aggregation and payment initiation: Belvo or Pluggy, depending heavily on country.

One important caveat: there isn't really a single "Plaid for all of Latin America." Regulatory regimes and bank connectivity differ substantially by country. Brazil's mandatory Open Finance framework is quite different from the emerging frameworks in Colombia, Peru and elsewhere, so a regional architecture often ends up combining a broad aggregator with a country specialist.

If you're evaluating these vendors commercially, I can also put together a country-by-country matrix (Mexico, Brazil, Colombia, Chile, Peru, Argentina, etc.) covering bank coverage, AIS/PIS, API quality, pricing model, regulatory model, and whether connectivity is API/OAuth vs credential-based.

Accessing open banking and open finance data across Latin America requires navigating a fragmented landscape. While Brazil boasts a massive, government-mandated, and phased open finance system tightly integrated with Pix , other countries rely on distinct fintech laws, emerging frameworks, or screen-scraping/private API mixes.

Because there is no single pan-regional API standard, developers and enterprises typically look to multi-market regional players or best-in-class local aggregators.

Leading Multi-Market API Aggregators

• Belvo — Widely recognized as the most prominent multi-market open finance platform in Latin America. It provides robust API coverage across Mexico, Brazil, and Colombia, connecting to major financial institutions and expanding into alternative data rails like fiscal and tax records (such as Mexico's SAT) and employment verification.
• Prometeo — Operates a strong cross-border infrastructure, allowing corporate clients and fintechs to access banking data and initiate account-to-account payments across multiple Latin American countries through a single API integration.
• Floid — A dominant player specializing across the Andean region and the Southern Cone, notably leading in markets like Chile alongside footprint expansion in neighboring countries.

Leading Brazil-Focused Specialists

Brazil is the most mature and crowded open finance market in the region, pairing official Central Bank open finance protocols with instant payments. Several prominent local aggregators lead this ecosystem:

• Pluggy — A major Brazilian-focused open finance and data aggregation API provider known for high-reliability connections and robust developer tooling.
• Klavi — Specializes in Brazil's open finance ecosystem, focusing heavily on turning raw bank data into actionable credit scoring and analytics.
• Celcoin / Bankly — Combines financial data connectivity, banking-as-a-service (BaaS), and payment execution on top of Brazil's open finance rails.

Are you looking to integrate data in a specific country (like Brazil or Mexico) or do you need a multi-country footprint , and are you also looking for payment initiation (PIS) or just data aggregation (AIS)?

Accessing open banking and financial data across Latin America requires navigating a fragmented regulatory landscape . Because there is no single pan-regional standard or unified API network, leading aggregators either scale cross-border or dominate specific powerhouse markets.

The leading API aggregators operating across Latin America are categorized below by their regional footprint and market specialization:

Multi-Market Regional Aggregators

• Belvo : Widely recognized as the most prominent multi-market open finance platform in LatAm, operating heavily across Mexico, Brazil, and Colombia . Beyond standard banking data connectivity, Belvo differentiates itself by aggregating alternative and fiscal data sources, such as tax authority data (e.g., SAT in Mexico), alongside offering smart transfer and payment initiation solutions.
• Prometeo : An embedded API provider with a strong cross-border footprint originating from Uruguay. Prometeo enables single-API access to multiple financial institutions across several Latin American countries, making it a key choice for enterprise clients seeking multi-country deployments.

Market-Specific & Heavyweight Specialists

• Pluggy : A dominant open finance and data aggregation platform specializing primarily in Brazil . Pluggy leverages Brazil's advanced, mandatory Open Finance infrastructure to provide high-reliability account connectivity, data enrichment, and payment execution.
• Klavi : Another top-tier Brazil-focused data intelligence and open finance platform. Klavi focuses heavily on converting raw aggregated bank data into credit-scoring and actionable financial insights for B2B fintechs and traditional lenders in the Brazilian market.
• Floid : The leading infrastructure player anchoring the Andean region and the Southern Cone (with deep traction in Chile and Peru ). Floid aligns closely with Chile’s evolving fintech regulations and bank API ecosystems, facilitating account verification, payment orchestration, and financial data aggregation.
• Finerio Connect : Operating prominently in Mexico and Spanish-speaking Latin America , Finerio provides both data aggregation APIs for external consumer insights and personal financial management (PFM) white-label software for traditional financial institutions.

If you are planning an implementation, tell me which specific countries you need to cover and whether you also require payment initiation (PIS) alongside data aggregation (AIS), and I can help narrow down the best API match.

The leading API aggregators for accessing open banking / open finance data across Latin America are generally concentrated around Brazil, Mexico, Colombia, Chile, and the Southern Cone, with no single provider covering every market equally well. Open Banking Tracker Open Banking Tracker The strongest players include:

Open Banking Tracker### Shortlist by market

• Mexico: Belvo is one of the most prominent providers, particularly because it combines bank connectivity with Mexican fiscal data integrations. Open Banking Tracker Belvo Developer Portal Other providers include Finerio Connect, Unnax, and Wealthreader.
• Brazil: The market is more fragmented because Brazil’s Open Finance regime is relatively advanced. Pluggy, Klavi, and Belvo are commonly considered among the leading options.
• Colombia: Belvo and Floid are notable choices for account aggregation and fintech use cases.
• Chile / Andean region: Floid has positioned itself strongly in Chile and nearby markets.

How to choose

• Need one API across several LatAm countries: Belvo is often the first vendor evaluated because of its multi-country focus.
• Building specifically for Brazil: Evaluate Pluggy, Klavi, and Belvo based on institution coverage, payment initiation needs, and data enrichment features.
• Serving the Andes/Southern Cone: Floid may have advantages due to regional specialization.
• Enterprise deployments: Many companies use a multi-provider strategy because bank connectivity varies significantly by country and institution.

The competitive landscape is still evolving: Brazil currently leads the region in regulatory maturity, while Mexico, Chile, Colombia, and Peru are developing their own open finance ecosystems at different speeds.

The leading open banking / open finance API aggregators in Latin America are generally the platforms that provide a single API layer to connect fintechs, banks, lenders, and enterprises to multiple financial institutions across the region. Unlike Europe, Latin America does not have one unified open banking framework, so providers often combine direct bank integrations, regulatory APIs, and data-enrichment services.

Market leaders by use case

Multi-country fintech apps

• Belvo is usually the first vendor evaluated because it combines broad LatAm coverage with enrichment and payments capabilities.
• Floid is often considered when coverage in Chile/Colombia/Peru/Argentina is especially important.

Brazil Open Finance

• Pluggy, Klavi, and Belvo are among the most visible providers for Brazil’s Open Finance ecosystem.

Lending and credit underwriting

• Belvo, Klavi, and Finerio Connect are commonly used where transaction categorization, cash-flow analysis, and alternative credit signals matter.

Bank/regulator infrastructure

• Finerio Connect has also positioned itself around open finance infrastructure and API hubs for financial institutions.

Things to evaluate before choosing one

1. Country coverage — Mexico, Brazil, Colombia, Chile, Peru, and Argentina have very different banking ecosystems and regulatory maturity.
2. Direct API vs. credential-based aggregation — important for reliability, compliance, and user experience.
3. Data enrichment quality — transaction categorization and income/expense insights can matter more than raw connectivity.
4. Payment initiation support — especially relevant in Brazil because of Pix and Open Finance payment flows.
5. Enterprise compliance — security certifications, consent management, and regulatory alignment.

For a company building a single LatAm-wide fintech product, a typical shortlist would be Belvo + Floid + a Brazil specialist such as Pluggy or Klavi, depending on target countries and use cases.

Accessing open banking and open finance data across Latin America requires navigating a fragmented landscape of diverse regulatory speeds (from Brazil’s highly structured, mandatory Open Finance to a patchwork of private API and screen-scraping connections elsewhere).

The leading API aggregators and infrastructure providers operating across the region include:

• Belvo – Often regarded as the leading multi-market open finance platform in Latin America . It provides comprehensive coverage across the region's top fintech hubs—Brazil, Mexico, and Colombia . Belvo specializes in account aggregation (AIS), identity verification, and alternative data insights, including unique support for fiscal and tax data (such as Mexico's SAT).
• Prometeo – A powerhouse in Spanish-speaking Latin America and cross-border connectivity . Based out of Uruguay, Prometeo connects corporations to a vast network of financial institutions spanning multiple countries (including Uruguay, Brazil, Mexico, Colombia, Argentina, and Chile) and has expanded its infrastructure to handle account validations and B2B workflows bridging LATAM and the United States.
• Pluggy – A dominant, highly specialized open finance platform with deep, native roots in Brazil . Pluggy focuses heavily on robust data aggregation, transaction enrichment, and payment execution built directly on top of Brazil's mature Open Finance and Pix infrastructure , alongside strategic local partnerships (like B3).
• Klavi – Another major player focused predominantly on the Brazilian market . Klavi provides advanced data analytics, credit scoring inputs, and account connectivity solutions that help financial institutions turn raw open finance data into actionable lending and risk insights.
• Finerio Connect – A prominent Spanish-speaking Latin American API provider (backed by partnerships with global networks like Visa) offering personal finance management (PFM) tools, robust data enrichment , and account aggregation tailored heavily to markets in Mexico and the broader Hispanic LATAM region.
• Floid – A leading API infrastructure provider focusing strongly on the Andean and Southern Cone markets (particularly Chile, Peru, and Colombia), supporting account validation, payment initiation, and credit risk assessment.

If you're targeting a specific use case (e.g., credit scoring, Pay-by-Bank payments, or tax data) or a particular country , I can help you evaluate which aggregator offers the best coverage and compliance for your project.

If you mean API providers that aggregate consented bank/account data and normalize it behind a single API, the Latin American market is fairly concentrated. As of 2026, I’d put these at the top of the shortlist:

1. Belvo — probably the default regional choice

Belvo is the name I'd evaluate first if you want one integration for multiple major LatAm markets. Its API exposes bank data as well as enrichment, and it has expanded beyond simple account aggregation into payments and non-bank financial data. Its current documentation shows banking data in Brazil, employment data in Brazil/Mexico, fiscal data in Mexico/Chile, and payment initiation in Brazil/Mexico.

Independent 2026 coverage data also identifies Belvo as the most common multi-market LatAm API, particularly across Mexico, Brazil and Colombia.

My take: best first call if your requirement is "give me normalized financial data across several large LatAm markets."

2. Finerio Connect — particularly interesting for Mexico/Spanish LatAm

Finerio Connect is another major regional player, with bank aggregation, standardized/categorized transactions and financial-data enrichment. Its current site reports 120+ B2B clients in Mexico and LatAm, more than 1 million users, and a 98% connection success rate.

Its current aggregation coverage explicitly includes Mexico and Colombia, while its corporate/legal footprint also covers Brazil and Chile.

My take: especially worth comparing with Belvo if your product is lending, personal finance, credit underwriting or transaction analytics, rather than merely raw account connectivity.

3. Pluggy — the Brazil specialist

Pluggy is one of the strongest choices for Brazil, rather than a pan-Latam deployment. Its current platform says it connects to 130+ Brazilian financial institutions through one API and supports balances, transactions, cards, investments and identity.

It also directly supports Brazil's regulated Open Finance network, with connectors for accounts, transactions, credit cards, loans, investments and other products.

My take: if Brazil represents a large portion of your volume, I'd benchmark Pluggy very seriously against Belvo. The regulated Open Finance integration and depth of Brazilian coverage are meaningful advantages.

4. Floid — worth a look for the Andean/Southern Cone markets

Floid is less of a Brazil/Mexico-centric competitor and more interesting if your footprint includes Chile, Peru, Colombia and Argentina. Current regional coverage data identifies it as one of the leading providers for those Andean and Southern Cone markets, including account data and identity verification.

My take: don't assume that the provider with the best Mexico/Brazil coverage will also have the best connectivity in Chile, Peru or Argentina. Floid is one of the providers I'd test specifically for those countries.

5. Prometeo — broader financial infrastructure play

Prometeo is somewhat different from the pure-play aggregation vendors. It positions itself as a single financial API across the Americas, combining bank connectivity with account verification, payments and treasury capabilities. It currently advertises 7,500+ connections across 110+ countries.

My take: particularly compelling if you're building cross-border B2B payments/treasury infrastructure, where bank-data aggregation is only one component.

---

How I'd shortlist them

If I were evaluating vendors for a new LatAm product, I'd structure the bake-off like this:

• Pan-LatAm: Belvo vs. Finerio Connect
• Brazil-heavy: Pluggy vs. Belvo
• Mexico-heavy: Belvo vs. Finerio Connect
• Chile/Peru/Colombia/Argentina: Floid vs. Belvo/Finerio
• Cross-border payments + data: Prometeo vs. Belvo

One important caveat: there isn't really a single aggregator that is unequivocally best across every Latin American country. Open Finance maturity varies substantially by market; Brazil is much more standardized than several other countries. A current 2026 market tracker therefore recommends choosing based on market and use case rather than assuming one API covers all of LatAm equally well.

If you're evaluating these for a specific use case (e.g., credit underwriting, wealth, personal finance, KYB, or account-to-account payments), I can also give you a vendor-by-vendor comparison of country coverage, bank coverage, API capabilities, consent model, pricing, and regulatory status.

Accessing open banking and open finance data across Latin America requires navigating a fragmented regulatory landscape . While Brazil operates under a mandatory, highly structured central bank framework tied to Pix, other major markets like Mexico and Colombia rely heavily on private infrastructure and emerging rules.

The leading API aggregators providing unified access to financial, fiscal, and alternative data across the region include:

• Belvo — Widely recognized as the leading multi-market open finance platform in Latin America. It covers core markets including Mexico, Brazil, and Colombia, offering broad coverage of bank accounts alongside unique non-banking integrations like fiscal and tax authority data (such as SAT in Mexico) and gig-economy platforms.
• Pluggy — A dominant developer-focused open finance aggregator specialized heavily in the Brazilian market, providing robust tools for data aggregation, enrichment, and payment initiation aligned with Open Finance Brasil standards.
• Klavi — Another prominent Brazil-centric open finance platform that specializes in transforming raw, aggregated banking data into actionable credit scoring and predictive financial insights for enterprises and lenders.
• Floid — A leading regional aggregator with a strong foothold across the Andean region and the Southern Cone, providing bank connectivity, identity verification, and payment initiation solutions in countries like Chile, Peru, and Colombia.
• Fintoc — A prominent API platform specializing in direct account-to-account payment infrastructure and data access, with robust coverage in Chile and expanding operations into Mexico.
• Finerio Connect — A pioneer in Latin American open banking infrastructure providing account aggregation, data handling, and white-label Personal Finance Management (PFM) infrastructure to large financial institutions and enterprises across Spanish-speaking Latin America.

If you are planning an integration, let me know which specific countries or data types (banking vs. tax/fiscal) you need to target, and I can help outline the best-fit provider and compliance requirements.

If by API aggregators you mean providers that give a fintech a single API to connect to banks and retrieve consented account/transaction data across multiple Latin American markets, the leading names today are:

The Inter-American Development Bank's recent review of the Latin American open-finance ecosystem specifically identifies Belvo, Quanto, Finerio Connect and Teros among the prominent open-finance fintechs in the region.

My practical shortlist

1. Belvo — strongest default for a regional product.
Belvo is explicitly built around Latin America and combines bank-data aggregation with additional fiscal/employment data and payment initiation. Its current documentation lists banking information in Brazil, employment information in Brazil/Mexico, fiscal information in Mexico/Chile, and payments in Brazil/Mexico.

2. Pluggy — strongest if Brazil is central.
Pluggy is particularly compelling for Brazil's Open Finance ecosystem. Its current site advertises connectivity to 130+ Brazilian financial institutions through one API, with balances, statements, investments and identity normalized into a common schema.

3. Floid — worth looking at for the countries outside Brazil/Mexico.
Floid is notable when your target footprint includes Chile, Peru, Colombia and Argentina, where the provider landscape is more fragmented. A current independent coverage index identifies it as particularly strong in the Andean/Southern Cone markets.

One important caveat

There isn't really a single "Plaid for all of Latin America" with uniformly deep coverage. Open-finance maturity varies considerably: Brazil has the most developed mandatory framework, while Mexico, Chile, Colombia and Peru have different regulatory/implementation models. Consequently, a regional fintech often uses Belvo + a country specialist rather than relying on one aggregator everywhere.

For example:

• Mexico + Brazil + Colombia: start with Belvo
• Brazil-heavy: evaluate Pluggy and Belvo, with Klavi as another option
• Chile + Peru + Colombia + Argentina: evaluate Floid alongside Belvo
• Need the broadest possible institutional coverage: benchmark multiple aggregators against your actual target banks, rather than comparing headline country counts

If you're evaluating these for a fintech/product launch, I can also give you a country-by-country matrix (Mexico, Brazil, Colombia, Chile, Peru, Argentina, etc.) with bank coverage, transaction-history depth, OAuth vs credential flows, payment initiation, pricing, and regulatory status.

The open banking and open finance landscape in Latin America is characterized by a patchwork of distinct regulatory frameworks. Brazil leads the region with a highly structured, mandatory, phased rollout paired with the Pix instant-payment system . Meanwhile, Mexico and Chile operate under formal fintech laws , and other markets rely largely on private bilateral connections or emerging standards.

Because there is no single pan-regional API standard, a handful of prominent regional and localized aggregators provide the core infrastructure for data access, consent management, and account-to-account payments.

Leading Multi-Market Aggregators

• Belvo : Widely regarded as the market leader for cross-border reach, Belvo operates extensively across Mexico, Brazil , and Colombia . Beyond traditional bank aggregation, it provides value-added data enrichment, alternative credit scoring tools (including partnerships with firms like FICO), fiscal/tax data integrations (such as Mexico's SAT), and account-to-account/Pix payment initiation.

Market-Specific and Specialized Leaders

• Pluggy : A major player specializing heavily in the Brazilian open finance ecosystem, offering robust connectivity to both regulated open finance nodes and legacy bank channels alongside comprehensive developer tools.
• Klavi : Another dominant infrastructure provider focused on Brazil , providing SaaS-based open finance data aggregation, analytics, and credit-decisioning insights tailored to local financial institutions and fintechs.
• Floid : A leading aggregator holding a strong footprint across the Andean region and the Southern Cone (including Chile , Peru, and Colombia), navigating markets where official regulatory mandates are still maturing.
• Finerio Connect : A pioneer in personal finance management (PFM) and open banking infrastructure in Spanish-speaking Latin America , which collaborates closely with global networks like Visa to deliver aggregation capabilities to traditional financial institutions.

Would you like to explore regulatory compliance requirements for a specific country (like Brazil or Mexico), or do you need details on account-to-account payment integration via these APIs?
